Ash-Shura - 42:14

وَمَا تَفَرَّقُوا إِلَّا مِن بَعْدِ مَا جَاءهُمُ الْعِلْمُ بَغْيًا بَيْنَهُمْ وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ إِلَى أَجَلٍ مُّسَمًّى لَّقُضِيَ بَيْنَهُمْ وَإِنَّ الَّذِينَ أُورِثُوا الْكِتَابَ مِن بَعْدِهِمْ لَفِي شَكٍّ مِّنْهُ مُرِيبٍ
[42:14]
And they did not become divided until after knowledge had come to them out of envy among themselves; and had not a word gone forth from your Lord till an appointed term, certainly judgment would have been given between them; and those who were made to inherit the Book after them are most surely in disquieting doubt concerning it.
And they became divided only after Knowledge reached them,- through selfish envy as between themselves. Had it not been for a Word that went forth before from thy Lord, (tending) to a Term appointed, the matter would have been settled between them: But truly those who have inherited the Book after them are in suspicious (disquieting) doubt concerning it.
And they were not divided until after the knowledge came unto them, through rivalry among themselves; and had it not been for a Word that had already gone forth from thy Lord for an appointed term, it surely had been judged between them. And those who were made to inherit the Scripture after them are verily in hopeless doubt concerning it.
